Lower back may bend slightly during hip flexion phase. Erector
Spinae is exercised isometrically if low back does articulate
as with Straight
Back Stiff Leg Deadlift (targeting Glutes). Begin with light
weight and add additional weight gradually to allow adequate
adaptation.
Throughout lift, keep arms straight. Knee can be kept bent throughout
movement. Do not stand behind pulleys. Do not pause or bounce
at bottom of lift. Do not lower weight beyond mild stretch throughout
hamstrings and back When finished with set, dismount by lowering
weight with knees bent and low back straight. Full range of motion
will vary from person to person. Those with less
flexibility may have to bend knees more or they may not even
need to stand on platform. See Dangerous
Exercise Essay. Also see Straight
Leg Deadlift.
